.SS "Configuration"
.sp
.LP
The \fBmr_sas.conf\fR file contains one user configurable parameter, for MSI or
MSI-X support. Configure your hardware through the related BIOS utility or the
MegaCli Configuration Utility. If you want to install to a drive attached to a
\fBmr_sas\fR HBA, create the virtual drive first from the BIOS (X86) before
running Solaris install. The \fBMegaCli\fR utility can be downloaded from the
LSI website.
.sp
.LP
The LSI MegaRAID SAS device can support up to 64 virtual SAS2.0, SAS1.0,
SATA3.0, or SATA 6.0 disks. The BIOS numbers the virtual disks as 1 through 64,
however in Solaris these drives are numbered from 0 to 63. Also keep in mind
that SAS and SATA drives can not be configured into the same virtual disk.
